Specification of Letters Patent.

Patented Nov. e, i917.

Application filed August 18, 1916. Serial No. 115,691.

To all whom t 'may Concern -Be it known that I, JAY B. Briones, a citizen of the United States, and va resident of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented cer- Vtain neiv and useful Improvements in pi e verst-i sectional view i drawings, 1indicated Dump-Cars, of which the following is a speciiication, reference being had to the ac vcompanying drawings.

My inventionl relatesto dump-car ofthe general type shown in my application for Letters Patent, Serial No. 98,1t95, tiled May 1 9, 1916, and particularly to the mechanism foi` controlling the operation of the plungers byivhich the body of the car is `dumped toward one side or lthe other and thereafter brought back to its normal horizontal position. lt -is the principal. object of my ini'entionto provide a form and arrangement vvvhereby the righting of the car-body may be effected properly and easily regardless of the amount of pressure which may have been required for dumping the car. The preferred means by which I have accom plished my objects are illustrated in the accompanying drawings and are hereinafter specifically described. vThat whichl believe tobe neWa-nd desire to cover-'by ythis application isset forth in the claims.` Y

'..In ,the drawings- Figure 1 s .a fragmentary view, being a transverse section taken across the car near one end thereof;

Fig. 2 is an enlarged detail, being a transverse sectional view through the exhaust valve; n

Fig. 3 is an enlarged detail, being a ltransthrough the stopfaiid- Waste cock by which the pressure from the train-pipexnay be removed ,from a lsingle cylinder `independently of the remaining cylinders.

Referring to the `several lfigures of the in which corresponding parts are by the same reference characters,

10-ll indicate longitudinally-extending I- beams comprising a portion of the main framework of acar. IPedestals lfoflanv suitable type are inountedupon the I-beairis ,10j-11 having pivotally connected therewith brackets 13 by which the body 1i of thecar 1s pivot'ally mounted ,so as to be adapted to 1b'e'tipped in either direction, as desired', for 'dumping the load. Transversely-extending beams l5 support cylinders 'i6- 47 provided with` plungers 18-19 respectively, ywhich are adapted to be raised relative tok the cylinders by steam or other suitable fluid. under pressure introduced through the train-pipes 'lO-Ql. Plunger-rods Q2 are pivf' votally connected with the plungers 18-19 at their lower ends `and at their upper ends are pivotally connected with transverselyextending links 23 which in turn are pivotally mounted upon brackets 2i rising from the Lbeams lO--11. B5- 526 indicate the members of thrustbars which are pivota ly connected at their upper'ends with blocks 27 carried by the bed 14, the loiverendsof the thrust-bars being pivotally connected with the bracketsli by means of links 28. The links are provided withy hooked arms Q9, pivotallymounted thereon, adapted to Aengage at their lower ends the outer ends of arms 30 which are vmounted upon rockshafts 31 which form a portion of the means for locking the car-body in normal hor` zontal position. Inasmuch'as theparts so far described are all of the type shown and described in my application Serial No 98,495 above referred t0,;it is not believed to be necessary construction or operation.

Referring particularly to FigfQ, 32 indicates a valve casing yadaptedto be connected between the train-pipe and the p'istpn,; it being understood 'thateach pistonis'prov vided with a valveof `this type. This valve comprises a. rotary valve -stem 'or plug^33 'interposed between an inlet chamber 3i and an outlet chamber 35, said plug beingprovided with a port which is adapted to be closed by rotation .of the plug 33 in either from the, position shown in Fig. inletchamber 34 is provided with asleeve` 37 provided` with openings 38 kin its side through which the steam or other fluid under 'pressure must pass. Other means is provided for closing the4 inlet chamber 34,

a proper direction to describev further their extending therethrough, 1

2. The v or gasket 43 mounted on the lower end of the stem 41 when such stem is held in its f lowermost position against t-he action' of the x tive to the pivot spring 40. The plug- 33 extendsoutward through the-wall of the casing 32, being provided at its outer end with a crank-arm 44 which is pivotally connected by means of a' link 45 with the link 23 `at that side of the car, the connection of the link 45 with the arm 44 involving a slot 45a adaptedv to permit the link 45 to-move downward relapin 433' without affecting the position' of the arm.

46 indicates a st op-and-waste cock interposed between the `valve 32 and the trainpipe. As best shown in Fig. 3, this cock comprises a rotary plug 47 provided with a port 48 extending therethrough and a port 49 communicating with-the port 48 and eX- tending at right angles therefrom. `When l the plug 47 is in the position shown in Fig.

' the stems 41 of the valves 32 in their upper- 3, free communication is afforded between the train-pipe and the valve 32 but when the plug 47 is given a quarter turn in counterclockwise direction in Fig. 3 by means of the handle 50 mounted upon said plug 47, it will be understood that the communication between the train-pipe and the valve4 32 will be cutoff and that the inlet side of the valve 32 ,will be opened to the atmosphere through the ports 49 and 48. It will be understood that when all the cars of a train are to be dumped simultaneously, the valves 46 will all be maintained in the condition shown in Fig. 3, the entire dumping operation being then controlled by the engineer at the locomotive. When, however, it is desired that all the cars of a train be dumped at the same point, rendering it necessary to dump one car at a time, the plugs 47 of all the valves 46 will prior to the dumping operation be given a quarter turn from the position shown in Fig. 3 so as to shut'off communication between the trainpipe and each of the valves 32. The dumping of each car is then controlled by the manipulation of the valve 46 of that car independently of the remaining'cars of the tram.

With'the valves 46 of the several carsof a train in the position shown in Fig. 3, with most positions closing the openings 38 of the sleeves 37, and with the car-bodies 14 all in normal 'horizontal position, when it is desired to dump the several cars simultaneously, the, engineer admits steam or other fiuid under pressure into the train-pipe 20 or 21 for operation of the plunger at that side of the car for dumping the car toward.v

the opposite side. The fluid under pressure, passing through the valve 46, comes in contact with the upper' face of the head 39, forcing the stem 41 downward against the action of the spring 40, serving toA uncover the openings 38 and t'o. close the exhaust port 42. The fluid under pressure is thus admitted to the lower end .of the cylinder 16 or 17, serving to force the plunger upward for dumping the car as described 1n my prior application Serial No. 98,495 above referred to. -As the plunger' moves upward, the link 45 is carried upward by reason of its .cnnection with the link23, serving tol turn'the plug 33 of the valve 32v in counterclockwise direction in Fig..2. The connections and proportions are such that the plug 33 serves to cut off' the. supply of fluid under pressure from the cylinder approximately when the plunger reaches its uppermost po-v sition. Then thereafter the pressure at the upper ends of the valves 32 is relieved by the manipulation of a proper valve at the locomotive, the pressure upon the upper faces of the heads 39 is relieved, permittin the springs 40-fto move the stems 41'upwar serving to lose the openings 38 and to open the exhaus ports 42. The plungers of the several cars are then free to descend by their own weight. forcing the steam or other fluid under pressure out'of the cylinders through the exhaust ports 42. In this movement, the links 45 move downward relative to the arms 44' until the upper ends of theislots 45*1 engage the pins 45". whereupon the plugs 33 of the valves 32` are again moved to normal position, ready for a subsequent dumping operation. If it is desired to have the plunger of a single car lowered for permitting the righting of that car separately, this would be effected through the manipulation of the valve 46 of that car serving to relieve the pressure at the upper end of a single valve 32 independently of the train-pipe.

It will be -understood that when thecars are to be dumped Separately` the pressure in the train-pipes 20-21 will be maintained constant. The fluid under pressure will then be admitted for the dumping operation through a proper manipulation of the plug 47 of the valve 46, and the pressure will be relieved in due time b v the proper reverse movement of the handle 50 of the valve 46 so as to permit the spring 40 to act to open the exhaust port 42.

When in the course of the downward weight the plug 33 is rotated sutiiciently to open communication between-'the youtlet have been entirely relieved through the ex-` haust port 42.

By the use of my improved mechanism the plunger' of each car is adapted to descend by its own Weight for exhausting the cylinder regardless ot' the pressure which was required in the cylinder :tor `dumping the car, the exhaust port from the cylinder being opened by the valve spring regardless of the amount of pressure inthe cylinder.

The plungers are thus insured against being forced down. in uiiexhaustedv cylinders, whereby there is nodanger at any time that any of the parts shall be broken by the operation of vrighting the car-body.
